For lance try to get element since it is best and the raw is not to high

do you realize that he ask help for low rank quest and the weapon you give is high rank?

Sorry, didn't notice it

LS= Just take the devil slicer or wyvern blade fire, I only use both of them until I reach nekoht, upgrade devil if possible, don't upgrade wyvern blade yet, it uses ruby which is hard to find, you might want to keep it first

sorry sam it was monster in p3rd and what gs or ls would be the best to fight 4* tigrex i currently use khezu shock sword gs and eager cleaver for ls and i wear most ceanataur armor and battle gauntlets to keep my speed sharpening

Excutioner is so bad, no sharpness, you can't even hit khezu, only the head, diablos sword might too hard, but hey, your choices, eager cleaver also should be enough, it probably the most elemental at low rank
